RAILWAY-TIE AND RAIL-r-FASTENINGV SPECIFICATION forming part of Letters Patent NO. 794,279, dated Julyll, 1905.

Application filed February 6, 1905. Serial No. 244,336.

To 0.5i whom it may concern:

Be it known that we,EDWIN CORNER BROWN, of the borough of Edgewood, and WALTER H. LAUMAN, of the borough of VVilkinsburg, Allegheny county, Pennsylvania, have invented a new and useful Railway-Tie and Rail-Fastening, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l shows in plan view a railway-tie constructed in accordance with our invention. Fig. 2 is a longitudinal section thereof. Fig. 3 is a vertical cross-section on the line III III of Fig. 1. Fig. 4 is a plan view of the end portion of the reinforcing-piece. Fig. 5 is a plan view of the clip for the rail. Fig. 6 is an edge view thereof, and Fig. 7 is a plan view of the reverse side of the clip.

The purpose of our invention is to provide a reinforced concrete tie for railways of such construction that it will be adapted interchangeably for use with rails of various sizes, so that the securing devices or clips for the rails may be readily attached, detached, and relaced without injury to the tie. The construction is of such nature that the tie is strong and durable and accomplishes perfectly the purposes for which it is designed.

In the drawings, 2 represents the body of the tie, which is made of concrete molded in a suitable die or mold and is reinforced by a metal bar 3, which extends longitudinally of the tie and is preferably of flanged cross-section. As shown in the drawings, it is of T shape in cross-section, and this we find to be the desirable construction. In the middle portion of the tie the reinforcing-bar extends through the middle portion of the body of the concrete; but toward its ends it extends upwardly, and at the rail-seat portions of the tie it is substantially flush with the surface. For the purpose of accommodating the bolts and clips or other securing devices by which the rail is held to the tie the reinforcing-bar 3 is provided with holes or marginal slots 4L, widened at their inner portions, as at 4l', and beneath the slotted portionsl of the reinforcing-bar there is a cavity or pocket 5 formed in the concrete, so as to give access to the under portion of the slot for the purpose of adjusting the bolt 6 therein. By thus bringing the reinforcing-bar to the surface it not only provides a better bearing or seat for the rail, but also affords means for holding and adjusting the bolts. The extreme end portions of the reinforcing-piece preferably extend downwardly in the concrete, as shown at The bolts 6 project through the slot 4 upwardly above the surface of the reinforcing-bar and receive the clips 7. rIhese clips are preferably made of square pieces of metal having on opposite sides middle shoulder portions c, which are spaced at different distances from the margin of the clip on its two sides, as shown in Figs. 5 and 7. The bolt-hole Z is also placed eccentrically to the middle of the clip, so that, as shown in Figs. 5 and 7, the center of the hole is at a different distance from each of the four edges of the clip. This provides eight different adjustments for the clip, for with one side uppermost it can be turned in each of its four directions, so as to bring the bolt-hole at a different distance from the center line of the rail, and by reversing it, so as to bring the other side uppermost, the unequal distances of the shoulder on the opposite sides of the clip from the margins of the clip enable it to be turned in four other positions, so as to give varying adjustments from the center line of the rail. In this way a clip of standard size can be adjusted to so many positions as to accommodate all the ordinary sizes of rails and also to accommodate the variations between the straight and curved portions of the track. The clip is set upon the upwardly-projecting end of the bolt and is secured by means of a nut 8, as shown in Figs. 1 and 2. The form of the securing device and other details may, however, be modified within the scope of our invention, and, if desired, the clip need not be capable of affording different adjustments by changing the side which is uppermost, the other adjustment of the clip being relied upon where four adjustments are sufHcient for the purpose.

The adjustable fastening-clip of our device may be applied to various uses besides that described, and we do not intend limiting its use with such rails and ties.

We claim# l. A reinforced concrete tie having a body of concrete and a longitudinal reinforcing-bar incased in the concrete and having integral portions bent upwardly and extending'through the concrete to form rail-seats; substantially as described.

2. A reinforced concrete tie having a body of concrete and a longitudinal reinforcing-bar of flanged cross-section incased in the concrete and having integral portions bent upwardly and extending through the concrete to form rail-seats; substantially as described.

3. A reinforced concrete tie having a body of concrete and a longitudinal reinforcing-bar embedded in the concrete and having portions extending upwardly through the concrete to form rail-seats, openings in said bar for the securing devices, and pockets formed in the concrete beneath said openings; substantially as described.

4. A clip having a marginal retaining-flange and shoulders on the top and bottom sides of the clip, the shoulders on one side of the clip being at a different distance from the margins of the clip than the shoulders on the opposite side of the clip; substantially as described.

5. A clip having a marginal retaining-ilange and shoulders on the top and bottom sides of the clip, the shoulders on one side of the clip being at a dierent distance from the margins of the clip than the shoulders on the opposite side of the clip, said clip having an eccentrically-placed hole for the securing device; substantially as described.

In testimony whereof we have hereunto set our hands.
